使用 amsthm 延续多页定理

Question

我使用amsthm来定义我自己的lemma、theorem和其他环境。有些太长，无法在一页上显示，这意味着它们被分成多页。

当这样的环境被分割时，我希望有一些文本，例如

定理 0.1（续）

和

引理 0.2（续）

或者环境的以下页面上有类似内容。我该如何实现呢？

\documentclass[%
    a4paper,
    11pt
]{memoir}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc} % Use 8-bit encoding that has 256 glyph
\usepackage[T1]{fontenc}
\usepackage{xcolor}

\usepackage{blindtext} 

\usepackage{amsthm}
\usepackage{thmtools}
\usepackage{etoolbox}

\usepackage{framed}
\colorlet{shadecolor}{yellow!15}


\theoremstyle{definition} %Also: plain, definition, remark
\newtheorem{lemma}{Lemma}[chapter] 
\AtBeginEnvironment{lemma}{\begin{shaded}}%
\AtEndEnvironment{lemma}{\end{shaded}}%

\theoremstyle{definition} %Also: plain, definition, remark
\newtheorem{theorem}[lemma]{Theorem} 
\AtBeginEnvironment{theorem}{\begin{shaded}}%
\AtEndEnvironment{theorem}{\end{shaded}}%



\begin{document}

\begin{theorem}
\Blindtext
\blindtext
\end{theorem}
\begin{lemma}
\Blindtext
\end{lemma}

\end{document}

该tcolorbox包可用于提供围绕定理等的可配置框，尤其是可轻松破坏tcolorbox。title after break={....}选项将显示一个特殊标题。

请注意，tcolorbox可以设置theorem自己的特殊盒子，但我保留了原始定义。
